| Abstract: | The design problem of touch screen based on S3C2440A is discussed, including its principle and structure of hardware. A system embedded ARM chip is applied to the touch screen development. The drive program of touch screen is developed. It uses the methods of reducing position error by mean value and interruption processing mode, that is, small task mechanism is used in driver development, and the program exists to quicken the whole system speed. |
